2mm 3mm Double Bubble Insulation Reflective Bubble Insulation for Window Fireproof and Heat Insulation
Double bubble insulation consists of two layers of polyethylene bubbles sandwiched between reflective foil layers (typically aluminum). The bubbles create air pockets that resist heat transfer, while the foil reflects radiant heat, providing dual thermal resistance. This design enhances insulation performance compared to single-layer alternatives.
How Does Double Bubble Insulation Work
Reflective Surface – The aluminum foil reflects up to 97% of
radiant heat, helping to maintain temperature.
Air Bubble Core – The bubble layer provides additional insulation
by trapping air, reducing heat transfer via convection.
Vapor Barrier – Many double bubble products also block moisture,
preventing condensation and mold growth.
Advantages of Double Bubble Insulation
Energy Efficiency: Reduces heating/cooling costs by blocking heat
transfer.
Lightweight & Flexible: Easy to cut, handle, and install
without specialized tools.
Moisture Resistance: Foil layers act as a vapor barrier, preventing
condensation and mold growth.
Durability: Resists punctures, UV degradation (if foil-coated), and
chemical corrosion.
Cost-Effective: Cheaper than rigid foam or fiberglass while
offering comparable R-values (typically R-6 to R-8).
Eco-Friendly: Often made from recyclable materials and reduces
energy consumption.
